TEACTION WHEEL f Application mea Marcil 2, 1925. serial No. 12,489.

This invention relates to a novel and im,-

proved traction wheel and more particularly to means for reinforcingV and strengthening Wheels which are not equipped with trac tionshoes, so that they may be so equipped is the principal object of my invention to lprovide a reinforcing meansy which may rbe readilyapplied to existing wheels, without material modification thereof.

A further object of my Ainvention is to provide a reinforcing means which maybe readily applied to the rim of a traction wheel and fastened thereto by means which also Vserve to hold in place the traction shoes mountedon the rim.

Arstill further object of my invention is* to provide a traction wheel having teeth co-operating with the rim thereof and fastened tothe rim, andjprovided with means for relieving the fastening means of shear,-

i ing stress, the arrangement being such that the teeth may be'readily applied to Wheels of standardmake. In the accompanying drawings in which I have shown a selected embodiment. of my invention. p l

Fig. l is an elevation of a portionvof. a Wheel of well known make having ,my `invention embodied therein. l

Fig. 2 is a circumferential :section of the wheel shown in Fig. l onfan enlarged scale, the section being taken normal to the axis of the wheel. Y Y

Fig. 3 is a section taken on the same vplane as Fig. 2, but showing one of the shoesinv a different position relative to the rim. l

Fig. l is a sectional view on the line 474.- of Fig. 3, but extended to show the h ub. 1

Fig. 5A is a section on the line 5-5 of Fig. 3. Fig. 6 is a detail view of one of the members of the supplementary rim.

Referring now to the drawings, the numeral l designates the' hub of a traction wheel of well known make to which are connected a plurality of spokes 2 joined at their outer ends to a rim 3. In this particular make ofwheel, the rim is formed of a wide plate secured at its edges to the spokes. Vhen such a wheel is to be supplied with traction shoes, it has been found that the rim is lacking in strength suflicient to prevent bellying thereof or other distortion or even breaking.

To provide sufficient strength so that the wheel-may be used with traction shoes, I

provide they rim with a supplementary rim disposed ypreferably on the Vinterior thereof 'and centrally between,A the edges so as to form a support for the shoes. `This suppleand still possess the requisite strength.v` It'l mentary rim lmay take a plurality of forms, l

as it is possible Vto make itA of any desired structural shape and `to makeit in one or` a pluralityof pieces. 'AI have shown, however, a form whichI have found to be very satisfactory in actual practice and in which form the supplementary rim is composed of a plurality of members of channel section. These members are identical and are `preferably made of a length, such thatpwhen ythey are placed `in overlappingposition as .plainly shown in Fig. 2, bolts may be passed through apertures therein and in the'rim 3 and willA be in a position to secure teeth l to the rim. These teeth are provided with lips 5 received within apertures in the rim so as to relieve the bolts of the shearings'tress thereon. The

teeth are connectedv together .by afbridgev member 6, which also acts as a holder engaging the transverse bar 7 of the traction shoe 8, to loosely secure the shoe to the rim.v The teeth, except as described above, and

the shoe, may be of any desired form, al-

though I have shownthem of they form described and claimed inthe co-pending application Serial No. 21,730liled April 18,/ 1925.

width, which may be foundv desirable or necessary totake up the shear, but Ihave found that these `lips may be relatively knarrow "thereby 'avoiding the necessity forV provid-v ing a vlarge aperture in lthe rim to receive them. The bridging member 6 acts to not only hold the shoe on the rim, but also to ktransmit shear from one tooth to the other so that the bolts 9, which pass through they ybridging member, tooth, rim and reinforcing members, and the lips 5 act together l VThel lips 5 may be made of any desired.`

rso

From the above it will be apparent that I have provided a traction wheel having a supplementary rim which may be readily applied to rims of existing wheels without necessitating any radical change therein. All that is necessary is the drilling or punching of the necessary apertures in the rim to receive -the bolts 9 and the lips 5 of the teeth. The

result is that a wheel, such asa wheel of the well known type illustrated, may be provided with these apertures and they may be used with orwithout the traction shoes as desired, it only taking a short time to install or remove the teeth, shoes and supplementary rim. When installed the teeth and shoes will have substantially the same advantages and mode of operation as set forth in my aforesaid copending application and the rim will be suffi ciently strong to support the shoes and transmit tractive effort without distortion or breakage. Y

I am aware that changes in the form, construction and arrangement of parts may be made without departing from the spirit and without sacrificing the advantages of the in` vention and I reserve the right to make all such changes as fairly fall within the scope of the following claims.

I claim:

l. A traction Wheel comprising a rim, and a supplementary channel shaped rim made up of overlapping members associated therewith to reinforce the same.

2. A traction whe-el comprising a rim, spokes connected with the rim at the edges thereof, and a supplementary rim vmade up of overlapping channel shaped members disposed between the spokes on the inside of said wheel rim and continuous therewith to reinforce the same. y

3. A traction wheel. comprising a rim, a supplementary continuous rim made up of overlapping channel shaped members disposed on the inside of said wheel rim, teeth on the outside of said rim, and a common means for fastening said teeth and said supplementary rim to said wheel rim.

4. A traction wheel comprising a rim, a continuous supplementary lrim made up of overlapping members disposed inside said wheel rim to strengthen the same, a plurality of teeth on the outside of said rim, and bolts passing through said teeth and said rims to secure them together.

5. A traction wheel comprising a rim, a continuous supplementary rim on the inside of the wheel rim and comprising a plurality of ing a channel having a relative-ly wide por tion lying against the interior of the rim and terminating in a relativelyA narrow portion bent inwardlyl away from the rim to overlap the relatively wide portion of the next member, and means securing said overlapping portions to said wheel rim.

8. A traction wheel comprising a rim formed of a plate, and a relatively narrow continuous supplementary rim made up of overlapping channel members disposed substantially centrally of'said plate on the inside thereof.

9. A traction wheel comprising a rim formed ofa plate, a supplementary rim disposed on the inner surface of said plate, said supplementary rim being formed of a plurality of members having overlapping ends, a

plurality of teeth on the outer surface of said` wheel rim, said teeth being placed in pairs opposite said overlapping ends, and means'pass-- ing through said teeth and said overlapping ends to secure the parts together.

10. A traction wheel comprising a rim, a supplementary rim secured to the wheel rim, said supplementary rim comprising a 'plurality of overlapping channel shaped members,

each member having a relatively narrow part and a relatively wide part, the wide part being adapted to receive the narrow part of an adjacent member.

11. A traction wheel comprising a rim,` a supplementary rim secured to the Wheel rim, said supplementary rim comprising a plurality of overlapping channel shaped members, each member having a relatively narrow part and a relatively wide part, said parts being offset and-the. wide part being adapted to receive the narrow part of an adjacent member.
